MESEP SP Surface Detectors for Conveyor Systems

Surface DetectorsSurface metal detectors for conveyor belts are electronic devices for detecting the presence of unwanted metal contamination in items moving along a conveyor belt. If you're worried about metal contaminants entering your process, and the conveyed item is fairly flat and no higher than 50 mm, then a surface detector is probably your best choice. Poorly maintained machines, the general wear and tear of the production machines are just a few of the ways that metal can enter your production process, ruin your grinder blades causing you thousands of dollars in production shutdowns.

Metal Detectors for Conveyor SystemsTo remove metals from your production process, a complete and total inspection of preassembled products is required to prevent these metals from leaving the plant and causing further damage. One possible solution involves examining the products at the end of the production line. Since all your products have to be transported to a conveyor belt at one time or another, a surface detector would be ideal for examining them while they are being moved to the conveyor.

Surface detectors are typically installed under the running belt cover. They can detect metal in the products above the running belt cover, but only in products that are not higher than 50 mm. Because they are located under the belt, they are not suitable for inspecting higher products, since their sensitivity decreases as the distance increases. The taller the product the less effective a surface detector will be. Anything higher than 50 mm is best analysed by a tunnel detector.


We offer a variety of surface detectors with varying detection capabilities in various module shapes. Choosing the right surface detector depends on the kind of product, its height and the type and size of metal to be detected. The MESEP AR surface detector is designed to be installed on a belt or shute conveyor. Only 35 mm high, this metal detector can be installed in places where space is limited. Availabe in three different sizes, these flat sensors can be installed side by side allowing you to scan a larger area. These detectors can also be arranged below and above the conveyor belt increasing the level of sensitivity.

Special Characterisitics Mechanics
  • No metal-free zones have to be considered.
  • Robust enclosure of high torsional strength.
  • Easy to Install.
  • External control electronics for band-stop or band-revers activation.
  • Reset automatic.
The MESEP® SP is available in a variety of widths from 200 mm to 850 mm. Because of its its robust aluminum continuous cast profile enclosure, the MESEP® SP is so strong even in larger widths that false detections of metal due to enclosure vibrations are avoided. The enclosure includes numerous tapped holes for easier installation.
The MESEP® SP provides maximum sensitivity and the great advantage of flush installation in metal parts.
